Thanks, Archie.
Hey Rage,
Combos such as these generally don't hold much value.A collector can just buy the one sheet for any of the films depicted.Once in awhile, if the artwork is different or the layout is cool they can be popular with collectors.Neither,really apply here.
I couldn't speculate on how rare it is.I would imagine,like a lot of combos,they wouldn't be the easiest too find.
